While the methods of collecting solar energy have improved drastically over the years, some of the most effective tools have been around for decades. Case in point: the Trombe wall, made popular by French engineer Felix Trombe in the 1960s, but...

In Boulder City, Nevada, the city council has paved the way for a fifth solar power array on 1,500 acres of land in an area called the Black Hills site, located in the Eldorado Valley Energy Zone. It did so by forging a development agreement between...

Under a new bill to be put before the Colorado House on Feb. 23, Colorado’s Office of Economic Development (OED) would be required to institute a study of the likely benefits of distributed generation from renewable energy sources like solar....

Take a look at any one of the concentrating solar power (CSP) projects in the U.S. and elsewhere, and you can see that – while CSP is undeniably the most efficient form of solar energy—the land needed (5 to 10 acres per megawatt) is considerable....

While the United States isn’t reaching its solar power potential, new information from the European Photovoltaic Industry Association makes it clear that over the past year growth has been substantial worldwide. In 2009, stymied by floundering...

Thanks to pioneering work at NREL, solar power manufacturer Amonix is now delivering commercially-ready, concentrated PV solar power “screens” that deliver 600 times as much electricity per square foot as standard solar PV panels. NREL is the...

It’s not good news, but it represents an all-too-human failing, one we call NIMBYism (not-in-my-backyard). Even if a project is beneficial, offering jobs and clean energy, some people don’t want it becoming part of the view out their windows. A...

First off, as I’m sure most of you are aware, Congress approved a one-year extension of 1603, the Treasury Grant Program, which pays cash grants for 30 percent of solar energy (and other renewable energy) installations in lieu of a tax credit,...

Good news out of Los Angeles, where the completion of a 1-megawatt (MW) solar power system covering 71,500 square feet will now allow ships docked between cruises to access some 1.2 million kilowatt-hours of clean, renewable solar power instead...

Unlike solar and wind power, wave energy still hasn’t captured the public imagination… perhaps because it still remains an untapped energy resource. There’s huge potential — over 2 terrawatts worldwide by some estimations — but, like other...

As Greg Jenner reported yesterday, there may be hope for solar funding in one version of the tax bill currently before the Senate. This version, a compromise between the Senate and the White House, was voted on today, Dec. 14, and includes a one...

It seems like everyone is pushing for a lead in the solar energy game. Who’s catapulting themselves into first place now? The world’s largest aerospace company, The Boeing Co. Boeing hopes to introduce their high-efficiency C3MJ+ solar...
